NAME

       XtGetSelectionValueIncremental, XtGetSelectionValuesIncremental - obtain selection values

SYNTAX

       #include <X11/Intrinsic.h>

       void  XtGetSelectionValueIncremental(Widget  w,  Atom  selection,  Atom  target,  XtSelectionCallbackProc
              callback, XtPointer client_data, Time time);

       void   XtGetSelectionValuesIncremental(Widget   w,   Atom   selection,   Atom   *targets,   int    count,
              XtSelectionCallbackProc callback, XtPointer *client_data, Time time);

ARGUMENTS

       callback  Specifies  the  callback  procedure  that  is  to  be  called when the selection value has been
                 obtained.

       client_data
                 Specifies the argument that is to be passed to the specified procedure when it is called.

       client_data
                 Specifies the client data (one for each target type) that is passed to the  callback  procedure
                 when it is called for that target.

       count     Specifies the length of the targets and client_data lists.

       selection Specifies the particular selection desired (that is, primary or secondary).

       target    Specifies the type of the information that is needed about the selection.

       targets   Specifies the types of information that is needed about the selection.

       time      Specifies the timestamp that indicates when the selection value is desired.

       w         Specifies the widget that is making the request.

DESCRIPTION

       The   XtGetSelectionValueIncremental   function   is  similar  to  XtGetSelectionValue  except  that  the
       selection_callback procedure will be  called  repeatedly  upon  delivery  of  multiple  segments  of  the
       selection  value.   The  end of the selection value is indicated when selection_callback is called with a
       non-NULL value of length zero, which must still be freed by the client.  If the transfer of the selection
       is aborted in the middle of  a  transfer  (for  example,  because  to  timeout),  the  selection_callback
       procedure  is  called  with  a  type  value  equal  to  the symbolic constant XT_CONVERT_FAIL so that the
       requestor can dispose of the partial selection  value  it  has  collected  up  until  that  point.   Upon
       receiving  XT_CONVERT_FAIL,  the  requesting  client must determine for itself whether or not a partially
       completed transfer is meaningful.

       The XtGetSelectionValuesIncremental function is similar to XtGetSelectionValueIncremental except that  it
       takes  a  list  of  target types and a list of client data and obtains the current value of the selection
       converted to each of the targets.  The effect is as if each target were specified in a separate  call  to
       XtGetSelectionValueIncremental.   The callback is called once with the corresponding client data for each
       target.  XtGetSelectionValuesIncremental does guarantee that  all  the  conversions  will  use  the  same
       selection  value because the ownership of the selection cannot change in the middle of the list, as would
       be when calling XtGetSelectionValueIncremental repeatedly.
